The invention, in general, relates to surface cleaning equipment and more particularly relates to an improved mop head for affording the effective mopping of floors in a' more expeditious manner and affording long life for the device. It is perhapswell known that'the majority of mops and mop. heads heretofore marketed for dry mopping' or partially dry and'partially'waxing a fioorsurface generally comprise a mass of individual strands of coarse fibre, string or yarn all, fastened together to a frame which is removably fastened to an operating handle. Some of these prior'm'opp'ing devices'consist of a pulpy mass of suitable, yieldable material encased in cloth or fibre. The former types of mops are disadvantageous because of the continual loss of individual strands of yarn, string or the like and the consequent reduction in' size of the mop head as well as ultimate loss of value entirely. Moreover, these former types of.mops become matted or cemented together by virtue of the accumulation of Wax. or other cleaning substance thereon. In both types, these disadvantages are reflected in poor mopping-operations and these prior mopsor mop heads have relatively short 1 v' w A primary object of the, present invention is to provide an improved mop head which is highly effective in cleaning floor surfaces in a minimum oftime, including the corners of the room, and which is extremely durable and has an increased period of use.

Another important object of my invention is to provide an improved mop head of the indicated nature which is additionally characterized by its lightness in weight permitting even slight women to handle the same readily.

A still further object is to provide an improved mop head of the aforementioned character which presents a firm but yielding mopping surface, and which cannot become soiled or lose any of its parts, or which otherwise deteriorates.

The foregoing and other objects are attained in a preferred embodiment of my invention which is illustrated in the accompanying drawings. It is to be understood that I am not to be limited to the precise embodiment shown, nor to the precise arrangement of the various parts thereof, as my invention, as defined in the appended claim, oan be embodied in a plurality and variety of forms.

Referring to the drawings:

Figure l is a plan view of a preferred embodiment of the invention showing the mop head attached to an operating handle, the latter being broken away to indicate length.

Figure 2 is a sectional view taken on the line 2 -2 ofFigure 1. f 1 Figure 3 is an end view of the preferred embodiment of the invention, looking from the handle end thereof. I Figured islai side elevational view of the'preferred embodiment of the invention, the operating handle for the same being shown in fragmenta'ry view.. In its preferred form, the improved mop head of'my'i'nvention preferably comprises a .molded body of relatively stiff but resilient material, such as rubber; 'saidbody being of generally triangular shape and having ahandle socket formed therein adjacent, to its wide end and being thickened atits wide end but tapering inthiokness .to' a relatively thin cross-section, at the apex'of the triangle of the body, "and means on said bodyfor detachably fastening a cover there- ;As particu1;ar;ly illustrated in Figures 1 and. 2 of the annexed drawinga my improvedmop head is formed toatriangular shape and preferably from molded-rubber, although any other material. havingi'he, characteristics of, relative stifl ness andyieldability or resiliency may be used. The molded rubber body of the mop head, which conveniently isl'designated by the reference '.nu-. meral ll. in the' annexedidrawings, also is pro videdwith a pair'of nibs I2"and I3 on its base [4' at opposite sides of the center thereof, such nibs being adapted to receive tie strings or the like of a cloth or fabric covering, not shown, for the mop head. In forming the mop head H, the edges of its sides [6 and II are formed straight while its apex I8 is rounded. Similarly, the junctures l9 and 20 between the base [4 and the two sides [6 and H are rounded thus eliminating all likelihood of fraying the rubber at these three points. I

In accordance with my invention, the molded rubber body II is formed to an appreciable thickness adjacent to the base l4 and of relatively thin cross-section adjacent to the apex [8, the taper between the base l4 and the apex l8 being gradual and uniform on both the top and the bottom of the body, all as clearly illustrated in Figures 2 and 4 of the accompanying drawings. Moreover, the body H is formed transversely with a reinforced section approximately at the center of the body; such reinforced section being indicated in dotted lines in Figure 2 and bearing the reference numeral 2| in Figures 1 and 2 of the drawings. In view of the triangular shape of the body H as well as the tapering thickness thereof, the reinforced. section 2| is of 3 generally triangular shape also and is somewhat thicker adjacent to the base it than at the apex l8 of the body.

In order to afford the attachment, in locking or latching relationship, of a suitable handle for the mop head, I provide a special type of handle socket 22 within an extension 22a of the mop head at the base end thereof. The handle socket 22 preferably is so formed as to define interior shoulders 28 and, M and is tapered so as to snug 1y receive and interlock with a tapered or oval shaped ball or bead 26 formed on the inner end 21 of an operating handle 38. The effect the latching of the handle in operative position, the handle 28 is reduced adjacent to the ball or head of the handle socket 22. This vconstruction is shown clearly in Figures 2 and 8 'o'f'the annexed It is to "be particularly observed that v the reinforcing section of the body II is carried drawings.

It is to be understood that the appended claim is to be accorded a range of equivalents commensurate in scope with the advance made over the prior art.

A cleaning head for a mop consisting of a generally triangular resilient body comprising a base, an extension projecting from the transverse center of said base; said extension having 7 a socket therein for the reception of a handle for the head, a pair of sides merging with said base, an apex at the juncture of said sides; said a-pe'xbe'ing rounded and the junctures between said base and said sides being rounded; said body having a relatively thick section at said base and uniformly tapering to a relatively thin section adjacentto-said apex, and a reinforcing section adjacent "to the transverse center of said body and extending from'the obverse as well as reverse of said'b'ody; said reinforcing section likewise being relatively thick in cross-section adjacent to said base and uniformly tapering 'to a relatively thin section adjacent to said apex.
